The genuine esrv_svc.exe file is a software component of Sony® VAIO Care by Sony Corporation.
Sony developed a driver file named "esrv_svc.exe" as part of its "VAIO Care" software for its VAIO laptops. Its function is related to monitoring power usage. User comments in forums seem mostly to concern adjusting screen brightness and whether it adjusts automatically, with which some users had problems after upgrading to Windows 8.1, especially if they did not update all drivers before the upgrade. If this program does not reside in "C:\Program Files\Sony\VAIO Care", possibly with a subfolder named "esrv", or if it is found in "C:\Windows" or its "System32" subpath, it is possibly disguised malware. Uninstalling is possible via the Control Panel, (select "VAIO Care"). There may be similar processes in other OEM's computers based on Intel's Energy Checker SDK (System Development Kit) with an "ESRV" tool for taking readings from onboard power analyzers, although this was being called "Whatif" software in 2010 and forum threads were archived.
